• Representing Label Generation Rulesets Using XML (RFC 7940) (170416 bytes)

Charter (as of 2015-10-14):

Domain registries, particularly those implementing IDNA (RFC 5890
et.al), usually maintain a set of criteria (or "ruleset") that governs
permissible labels allowed for registration, such as [IANAIDNTABLES].
These rulesets are commonly a mixture of eligible code points along
with contextual criteria that must be met concerning the positioning of
certain code points. Some registries also specify rules regarding
variant labels and how they are to be handled. Domain registries
commonly need to share these rules, but there is no interoperable format
that can be used that can support many common use cases. This group
seeks to produce such a format, which will enable re-use and sharing of
existing rulesets, and simpler implementation of new rulesets in registries.

A comprehensive format specification has been developed, named Label
Generation Rules, primarily to support the rules to be used for the
DNS Root Zone [Davies]. This group will use this specification as a
starting point to develop a common XML language that provides a superset
of functionality of current specifications
[RFC 3743, RFC 4290, et.al], along with other known use cases. This
single format is expected to supersede existing formats, and form the
basis for future rulesets used at different levels of the DNS hierarchy.
